And Google News shows us Watson is right so far – only the IoS appears to have picked up the solicitor general’s response to his question about the investigation of the News of the World phone hacking case.

Mr. Tom Watson (West Bromwich, East) (Lab): Will my hon. and learned Friend satisfy herself that the Crown Prosecution Service has not successfully prosecuted cases on the basis of police files that were compiled using evidence illegally obtained by News of the World phone hacking?

The Solicitor-General: Yes – I am not sure that any connection has been made, but I am very well aware of the issue, and it is an issue well raised.

Further to that, the Independent on Sunday reports:

Whitehall sources said that there would not, at this stage, be a full-blown investigation into any concerns, but that the issue would be examined. A more detailed investigation would take place if substantial evidence was put forward, sources said.

According to the paper: “a spokesman for the Met said it would not be commenting on the parliamentary exchange. A News International spokesman declined to comment.”
